Telescopic Guides: Load Capacity

This is perhaps one of the most frequently asked questions in the industry: How much weight can telescopic guides support? The question may seem easy to answer, but it is not. What does it mean when we say that a particular model of the telescopic guide can support a certain load in kilos? What information may be implicit in the data they provide? What is important to know? If you want to find the answers related to the load capacity of a certain telescopic guide… this is your article.

If we are asked about the weight that a telescopic fence supports, we should refer to its load capacity. The load capacity depends on several factors, let’s see the main ones.

The Model Of Telescopic Fence

Each model is designed to withstand specific load levels. The larger the profile of the telescopic fence, the greater its load capacity. Find out more about all the telescopic bar models according to their load capacity here.

The Relationship Between The Length Of The Guide And The Extension

Within the same model, the extension of the guide also determines its load capacity. If the extension is understood as a percentage of the bar length, the greater the proportion, the lower the load capacity. This has to do with the number of balls we can place in the fence, which are the ones that support the weight. This means that the greater the number of balls, the greater the load capacity. When we increase the extension of a guide (keeping its length fixed), we reduce the number of balls and therefore its load capacity.

The Estimated Number Of Cycles

All mechanical components wear out with use and lose their performance. The more use, the more wear. It is not the same to open a drawer loaded with 200 kg. four times a day as to do it once every two months. If the number of cycles a pair of guides will be subjected to in its lifetime is very low, it can be assumed that its load capacity will be greater than if the same guide were subjected to a much higher number of cycles. In other words, if usage is going to be more intensive, the useful life of the telescopic guide will be lower. For this reason, the load capacity data will always be related to a number of usage cycles. One data without the other would be meaningless.
